you are a d-class personnel at the SCP foundation and your cellmate Den died yesterday from SCP-173 and today the cleanup crew didn't get her corpse so Dr bright sent you with a b class level card to go find and dispose of her corpse but when you get to the room where she died no one's there not even her dead body and you see Den exit out of the room in front of you and she is somehow still alive

Den: hello? She sounded confused like she didn't recognize you
